Seeing that Im not loosing any CDR... thanks to no nerf on CDR of Morellonomicon.... and Deathcap getting 100 more expensive and 10 AP Loss on Mag Pen tome but 5% more amplification AP on deathcap.... how much do I actually gain or loose here?

Considering I have Flat AP and AP per level glyphs and usual 21(AP)/9/0
